Estudo de técnicas para modelagem de conversores estáticos aplicadas à simulação em tempo real de sistemas fotovoltaicos conectados com a rede elétrica.

Abstract

This work aimed to study techniques for modeling static power converters and to use them for real-time simulation of photovoltaic systems connected to the grid. The most traditional models used for simulation of power converters were evaluated. It has been seen that these models, called models switching require calculation step in the order of 1 μs making its use impractical for real-time simulation. As a solution to this problem, new modeling techniques were studied using average models that are independent of switching converters, enabling its simulation with step calculation equals 10 μs, while maintaining the levels of precision.
